The straight line, L1, has equation y = -1/2x - 2 a. Write down the y intercept of L1.

b. Write down the gradient of L1.

The line L2 is perpendicular to L1 and passes through the point (3, 7).

c. Write down the gradient of the line L2.

d. Find the equation of L2. Give your answer in the form ax + by + d = 0 where a, b, d ∈ z

The function c(n) below relates the number of bushels of apples picked at a pick-your-own orchard to the final cost for the apples. it takes as input the number of bushels of apples picked after paying an entry fee to an orchard and returns as output and returns as output the cost of the apples (in dollars)c(n) = 15n + 30which equation below represents the inverse function n(c), which takes the cost of the apples as input and returns the number of bushels picked as output
